SCIENCE AND INDUSTRY.
Manufacturing Is active al through
the New England 6tatos, especially in
the textile mills, E
In Southern Arizona business Of all
kinds IS increasing in volume, and the
mining and cattle industries are as
Stunning large proportions. :
Eastern parties are making ar
rangelnents for the establishment OF
boiler and machine factories at Ia
coma, w. 7. The iron to be used will
come from neighboring mines.

L. Noes has found that to drive straws
into pine boards and hickory bark, as
is often done by tornadoes, q velocity
of $50 to l75 miles an hour is noces-
sary.--Arka',saso Traveller.
The beautiful wood mountain ON
the Arctic island of New Siberia was
visited in the summer of last year by
Baron Won Toll. Russian explorer.
The side of this mountain discloses fos-
sill tree trunks and impressions Of
leaves and fruits In the tertiary rocks.
.---N the cephalopods. comprising the
cutie fish. the octopus, or devil-tish,
and their allies, thirty-two species new
to science were discovered by the Chal-
longer expedition, according to a report
just finished. Some of the cophalopods
have q length of sixty feet, and they
appear formidable as we'll as singular
creatures. -Ark0asow Traveller.
There are 20 blast furnaces in and
about Pittsburgh, IS rolling mills, 80
steel works. ID window glass works. 81
fliat-glass works and II green glass
works. The blast furnaces make 9O0,-
600 tons of iron per year, the rolling
mills $4,000 tons, steel works 100000
tons, plate glass works 8. $50, 900 square
feet. window glass works 100000.
"A remarkable proof of the protect
tive instinct of birds is reported from
South America. In Chilli the fruit of
the year is said to have caused the
death of many sheep aud cattle when
fed to them in large quantities. The
birds, however, did not touch the fruit.
From this fact it is argued that the in
stinct Of birds in respect to fruit may
we'll guide man in regard to eating it;
aad the further suggestion is made that
the condition of the fruit crop of a par
ticular season may have something to
do with outbreaks of epidemic disease,
such as cholera.-M. T. Ledger.
The remarkable industrial and
commercial progress made in the South
ern States during the past few years
has been widely noticed. An i'm
portant feature of this is found in
the comparative freedom from labor
troubles, which in nearly every other
section of the country have caused so
much disturbance. Leading Southern
papers have recently called the atten-
ton of manufacturers and others to
this as an inducement to embark in
Southern business enterprises, and this,
" it'll natural advantage at the South.
has induced many to start in business
there. Br0dstreet'S.
According to recent experiments of
MN. Hauriot and Richet, Of which an
account has been given to the French
of Sciences, the ventilation of
the lungs is increased by muscular
labor. In moderate work the vcntila-
ton is more than sufficient for the ex-
erection of the carbonic acid produced,
and above all for the absorption of the
necessary oxygen. In hard work the
of carbonio acid produced
and oxygen absorbed rise slightly the
harder the work; but it is chiefly the
of carbonic acid which in
creases. During u cular exert;on the
ratio of carbonic acid produced to
oxygen absorbed tends to become unity,
normally it is less than unity.
